PAUL M. KEMTER NID ARTHUR W. HENTSCHEL, OF WEST NEW YORK, NEW JERSEY.

WHEEL-TIRE.

To all 'whom 'it may concern: v

Be it known that We, PAUL M. KEMTER and ARTHUR W. HENTSCHEL, citizens of the United States, residing at'VVest New York.

in the county of Hudson and State of New" Jersey, have invented cert-ain new and useful Improvements in VVheel-Tires, of which the following is a specilication.

This invention relates to improvements 1n tires, more particularly tothe class of yieldable tires employed upon automobiles and like vehicles, and has for its object to provide a simply constructed wheel tire which will possess the requisite yieldableness to enable it to be employed upon automobiles and like vehicles without employing air under pressure to produce the rot-undity of the tire. 4

With this and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim; and, in the drawings illustrative of the preferred embodiment of the invention, Figure 1 is a side elevation, partly in section, of one of the improved tires, to-

ether with one of the wheel rims to which it is attached; `Fig. 2 is an enlarged section on the line 2-2`0f Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improvement may be applied to vehicle wheels of various sizes, and to wheels employed for various purposes, but, as before stated, the invention is more particularly applicable to the Wheels of automobiles and like vehicles, but it will be understood that it is not desired to limit the. invention to any specific arrangement'of-wheel or to wheels employed for any specific purpose.

The improved device is readily adapted for application to the ordinary metal rim of an automobile wheel, or to rims having the turned over or clenching edges, and for the purpose of illustration is'shown applied to a rim of this character, the turned over rim being represented at 10 and the felly portion of the wheel at. 11.

The improved tire includes in its construction an endless tubular body formed from a single coil of wire, and represented as a whole at 12, and'curved to conform substantially to the wheel and with its'ends firmly united, as by soldering or braaing, as indi- Specication of Letters Patent.

Application led December 14, 1910.

cated at 13. By this means the bod)T continuous throughout and will be of sutiicient weight or gage of wire to resist the strains to which it will be subjected, while at the same time being sufficiently vieldable to insure the requisite yieldableness of the wheel. Bearing upon the outer portions of the circle of coils is a wear member 14, preferably of sheet metal and curved to conform to the outline of the coil and bearing over the outer portion onlyT of the same. Surrounding this body of coils and the wear member 14 is an inner sheathing 15 of fabric, preferably heavy canvas and secured in any suitable manner at the edges, as for instance by lacing, as represented at 16. The sheathing 15 is formed with an inner shorter section 22 directly in contact with the wear plate 14 and reduced at its edges, and bearing upon the inner sheathing 15is a layer 21 of fabric, preferably canvas and covering the outer portion of the inner sheathing only, or being located where the greatest wear and strains will occur. By this means the tire is materially increased in thickness at the outer portion to increase the resistance where most needed. ner sheathing 15 the outer fabric layer 2l and the reinforcing strip 14 is an outer sheathing 17 of raw hide or similarmaterial, which is impervious to puncture and like injuries. The edges of the outer sheathing are enlarged, as shown at 18, to engage beneath the clenching flanges of thel rim 10 in the same manner that an ordinary automobile wheel tire is supported. Bv this means the out-er sheathing lnay be firmly clamped in position and hold the tire in place, while at the same time presenting an impervious surface to the road over which the wheel operates.

At suitable intervals the three members 15, 21and 17 .are secured together by rivets or other suitable fastening devices, 19, and additional rivets or like fastening devices 20 are supported in the outer sheathing 17, the heads or outer ends of all of the rivets forming. protectors, or wear members to engage with the surface of the ground and thus protect the general surface of the outer sheathing. Any requirbd number of the rivets or similar devices may be employed, and they willI extend as faras necessaryA from the center to amply protect the outer sheathing.

Prac-tice has shown that rawhide for the Bearing around the. in-

outer sheathing and heavy canvas for the inner sheathing meet the requirements, but it will be understood that any other suitable substance or material may be employed for these purposes. Amy suitable metal may be employed for the coil 12, but steel will generally be employed, and may be galvanized v or otherwise treated to prevent corrosion.

Having thus described the invention, what is claimed as new is:

A tire of the class described comprising an outer sheathing of rawhide having clenoher enlargements, a core formed from a single coil of'wire7 a sheet metal Wear member curved transversely to conform `to the curvature of the core and bearing around the outer portion of the same, an intermediatefabrie member between the outer -member Copies of this patent may be obtained for and the core and detaehably united at its edges, a fabric enlarging member betweeIL 20 the outer portion of theouter member and the intermediate member, a fabric enlarging member between the outer portion of the intermediate member and the met-a1 wearmember, and fastening?,r devices extending through the outer sheathing the, intermediate member and the enlargmg member, said fastenve cents each, by addressing the Commissioner of Patents, Waishington, 1350"
